Hey Guys

Not sure about GVs in other coutries, but I'm sure there isn't enoguh room under the hood in a North Amercian GV for another battery. You would have to put it in the rear cargo area in a battery box. Get an Optima battery (sealed) so you don't have to worry about it venting anything into the interior.

There is almost no room for anything else under the hood...even with a J20A powerplant. The only option will be in the trunk. Even if you are thinking of fitting a higher capacity battery in the original position, the space is quite limited.

Please correct me if I am wrong, but wouldn't anything higher than the OEM spec battery be a bit taxing on the alternator....thus might cause an early failure...in theory? Wouldn't this also be having any side effects to the ECU module?

No and No.

The alternator has essentially two functions - to provide electrical power to operate the vehicle and it's accessories, and to recharge the battery, replacing the energy used to start the vehicle.

A larger battery, by itself, does not change either of these requirements, so there will be no additional load on the alternator. What needs to be considered here is the reason the original poster wants to fit an additional battery - if the reason involves additional electrical load than the alternator may be affected.

With regard to side effects on the ECU - it plays no part in the electrical system of the vehicle, as long as the supply voltage remains within normal operating limits (roughly 10~15VDC), the ECU will function just fine.

I have been thinking the same, since I will have a winch on mine soon.

I don't want to put it inside, so I have been thinking about putting "some" batteries under the driver and passenger doors (I can make them fit in on the inside of the chassis rails) I already have an air tank under the drivers side, so maybe I can only fit it on the passenger side.

I will have to make up some brackets and armour so that I will not damage the battery or batteries (what ever I choose) when I'm out and about.

My Winch will draw a max of 500~600 Amps at peak load, and I also want the extra battery for a Fridge.

I have not fitted the battery YET... Read my post again...

Anyway, I figured that since I HAVE managed to fit an air tank under the drivers side, It must be possible to fit a battery under the passenger side.

I have a lot more room, since mine is lifted, and I have the sidesteps on it. I have about 20-25cm between the floor of the body to the lowest sidestep bracket. It should be possible to find a deep cycle battery that will fit there, and to make some kind of waterproof battery canister. I was even thinking about installing it in an old ammunition box.

Its all still just ideas in my head, since I'm busy getting bullbar and winch, and also in the middle of manufacturing a really nice roof rack for it..

Once the bullbar is in, I also plan to install a hot water system for shower etc, this will go somewhere inside the engine bay, perhaps in the front of the radiators.

Too many projects, not enough time... But, thats how it is with a hobby...

Found this one...may suit your needs.

Autocraft - Electrical [Suzuki Vitara Dual battery]

I emailed for some info and this was the speedy reply..

We have the battery boxes in stock at $170 which take 3 x 18amp hour deepcycle agm batteries. These sell for $92.00 each. We usually connect them inusing an 175 amp anderson plug so the batteries can be removed at any time.Some people prefer using a strap to hold the battery box in while some wehave welded lugs onto the box and bolted it in place. Cabling is then run tothe front of the vehicle to the main battery using a Redarc electronicisolator, we can supply the Redarc 100amp isolator for $132.00 if required
